FIREARM.

Application filed December 3g 1921, Serial To all @07m/m, t may concern.'

Be it known that I, CARL GUSTAF Swinn- LrUs, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful improvements in Firearms, of which the following is a full, clear, concise, and exact description.

This invention relates to firearms and more especially to sporting rifles vof the single shot type.

In riiies of the single shot type now on the market, it is necessary, when loading, to

manually partially chamber the cartridge by pushing the nose thereof into the bore of the barrel a sucient distance so that the cartridge is in axial alignment .with the barrel to allow the breech bolt, when closing, -to thrust the cartridge the rest of the way 0 into the barrel without jamming.

It is the object of this invention to render unnecessary the manual positioning of the cartridge in the barrel, when loading a gun of this type. This object is accomplished by providing means within the receiver of the gun for automatically positioning a cartridge in axial alignment with the bore of the barrel. The 'breech bolt on closing thrusts the cartridge the whole distance into the barrel. The cartridge may thus be merely dropped through the loading opening into the receiver and will be chambered without being touched further by the operator of the gun.

Further objects and advantages of this invention will be apparent from the following specification and accompanying drawing wherein Fig. 1 is a side elevation of a gun embodying the invention with the breech open; Fig. 2 is a similar view of the receiver with the side plate removed; Fig. 3 is a view similar to Fig. 2 with the breech closedl and Fig. l is a plan view of the receiver with the top wall broken away.

Referring now to the drawing 10 is the receiver, 11 the stock, and 12 the barrel. A breech bolt 13 is reciprocally mounted in the receiver and when in its forward position completely closes a slot in the right hand wall of the receiver formed between the top of the receiver and the removable side plate 14. A locking lever 15 is pivotally mounted on the breech bolt 13 and abuts against the stop 16 to lock the breech No. 519,843. Renewed November 17, 1925.

bolt in its forward position. Extending at right angles from the main portion of the locking lever is a lug 17 on which is provided a stud 18. Extending from the front wall of the receiver is a rod 19 upon which is reciprocably mounted the handle 20. The action slide 21 is attached at its front end to the handle 2O and is provided at its rear end with an aperture in which is received the stud 18. rl`he hammer 22 is pivoted to the side wall of the receiver and extends through a slot in the top wall to the rear of and in alignment with the breech bolt. A trigger 23 is pi votally mounted in the bottom wall of the receiver and cooperates with the hammer to hold the latter in cocked position.. Reciprocation of thehan'dle 2O is effective to move the breech bolt to open and close the breech and to set the hammer in cocked position.

A cartridge support 24 is mounted on a stud 25 carried by the side wall of the receiver slightly below the bottom of the breech bolt and at a point slightly in advance of the front end of the breech bolt when it is in its rearmost position. The support extends forward nearly to the front wall of the receiver and is provided at its rear edge with an upper extending lip 26 to position the cartridge laterally of the receiver. A spring 27 tends to move the front end of the support to the position shownaign Figs. 1 and 2 and a pin 28 carried by the support and working in a groove in the side wall limits the pivotal movement of the support. When the breech .bolt is in its rear position, the spring holds the forward end of the cartridge support in its upper position but Vas the breech bolt moves forward it depresses the support to a position where a cartridge carried by the support is in alignment with the barrel and is in proper position to be chambered by the closing of the breech. A leaf spring 29 is attached at one of its ends to the upper wall of the receiver and extends toward the front wall of the receiver. The forward end Of the spring is turned down slightly and terminates adjacent the rim of the cartridge chamber.

To load the gun it is necessary only to pull back Von the handle 20 to move the breach bolt to the rear and open the slot in the receiver. The cartridge support then assumes the position shown in Figs. 1 and 2. A cartridge is then slipped through the slot in front of the breach bolt onto the support 24, said slot being the 'only place through which a cartridge can be inserted into the gun. The cartridge assumes a tilted position relative lto the barrel because of the fact that the forward end ci the support is in its upper position and the position of the cartridge laterally of the receiver is determined by the lip 26. The handle 20 is then moved forward and the breech closed. When the breach bolt engages the upper surface of the support 24 the front end of the support is moved down to its normal position bringing the cartridgeinto alignment with the bore of the barrel. rlfhe spring 29 cooperates in this operation by directing the 4nose of the cartridge into the chamber. The bolt then pushes the cartridge forward and chambers it. The cartridge is thus automatically chambered and it is unnecessary to manually direct the cartridge into the chamber.

It is to be understood that various modilications may be made in this device without in any way departing Vfrom the spirit of the invention as set forth in they following claims.

lVhat is claimed is: e
